As we reported over the weekend, Microsoft and its partners are finally realizing that Windows Phone won't simply sell itself -- it has to put some money and marketing muscle behind the platform.

There also needs to be an emphasis on better hardware for the Windows Phone platform. Nokia will do its part with the Lumia 900 at a press conference later today, while HTC is already onboard with the HTC Titan II. The Titan II is the first LTE smartphone to grace AT&T's nascent network.

“HTC’s history of innovation in 4G technology includes delivering the first 4G-powered devices to each major carrier in the U.S., so it is exciting today to continue that leadership with our first 4G LTE Windows Phone, the HTC TITAN II,” said Peter Chou, CEO of HTC Corp. “This full-featured smartphone combines HTC’s design with AT&T’s high-speed 4G LTE network and Microsoft’s powerful Windows Phone software, giving people more of what they crave.”

We don't yet having any pricing or concrete availability details for the HTC Titan II. All HTC will say at the moment is that it will be available in the "coming months".
